Stupid question, but it has to be asked…

Fifth position. Front leg — is the knee slightly relaxed in front of the back knee?

Obviously you want to hold your back knee as straight as you can, and you can do that. There is nothing getting in the way of you straightening that knee. But what about the front knee? Is it supposed to be completely straight? Or like as straight as you can get it, without breaking contact with your feet?

And if the latter is true, then aren’t you really doing all the pulling up etc. and keeping your back leg completely straight but sort of hugging your front knee to your back knee?

I find that often when I am looking at people standing in fifth position, their front knee looks slightly bent. Now, there are those people who are obviously bending both legs to be able to twist their feet into a closed fifth, and I’m NOT talking about them. I’m also not talking about those painful-to-look-at photos of people rolling their ankles in to stand in faux fifth — these ones often seem to go hand in hand with the both-knees-bent photos. No, I’m taking about beautiful closed fifths where the back leg is straight as can be but the front knee looks a smidge curved around the front knee. Just a smidge. 

SO confused about this! Maybe it is just a body shape thing? Maybe those extra bendy people can keep their legs completely straight and twist their ankles to also be able to keep complete closed contact at their feet as well?

And which is more desirable? Closed feet with slight curve in the front knee? Or completely straight legs but an open fifth at the feet?

I would assume whatever is healthier for the body is correct. So whichever is going to cause less harm and injury — but which is that? Is it harmful to have a slight curve in the front knee, if everything else is in correct alignment? Does it actually allow less twisting of that front knee, which might even be healthier?

Anyone feel like educating this confused wannabe? :/
